John Wesley on Acts 13:36

David, having served the will of God in his generation, fell asleep - So his service extended not itself beyond the bounds of the common age of man: but the service of the Messiah to all generations, as his kingdom to all ages. Served the will of God - Why art thou here thou who art yet in the world? Is it not that thou also mayest serve the will of God? Art thou serving it now? Doing all his will? And was added to his fathers - Not only in body. This expression refers to the soul also, and supposes the immortality of it.
